A OEMEYS 3,001,487 INCINERATOR Paul J. Meyer, 401 N. Vale St., Jefferson, Tex. Filed Apr. 15, 1960, Ser. No. 22,579 1 Claim. (Cl. 1111-25) This invention relates to a novel and improved incinerator, for such as garbage and other trash.

The primary object of the invention is the provision of a more eflicient, more easily used incinerator of generally advanced construction, which has a low-placed emptying opening in its sidewall which renders emptying of the incinerator of unconsumed material, such as cans and bottles, retained by its grate, and which has an angled grate which declines to the emptying opening whereby such as cans and bottles are automatically conveyed to the opening and the need for reaching into the incinerator, for the purpose of removing the same, is eliminated.

Another object of the invention is to provide an incinerator of the character indicated above which is provided, beneath its grate, with a slide-out ash drawer which receives all material passing downwardly through the grate, and is easily taken out, dumped, and replaced.

A further object of the invention is the provision, in an incinerator of the character indicated above, of a burner, such as a gas burner, which is located immediately beneath the grate, is slanted at the same angle as the grate, and is centered with respect to the grate, at the upper part of the grate, whereby material deposited on the grate is subjected to greater combustion at the upper part of the grate before sliding along the grate to the lower part of the grate, or falling through the grate, the grate having inwardly angled ramps at its sides which serve to convey material deposited in the incinerator toward the center of the grate.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is a perspective view of an incinerator of the invention;

FIGURE 2 is an enlarged fragmentary vertical transverse section taken on the line 2-2 of FIGURE 1;

FIGURE 3 is a vertical transverse section taken on the line 3-3 of FIGURE 2;

FIGURE 4 is a horizontal section taken on the line 4-4 of FIGURE 2; and,

FIGURE 5 is a fragmentary horizontal section taken on the line 55 of FIGURE 3.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated incinerator comprises a flat rectangular pan-shaped base having a bottom wall 12, surrounded by upstanding walls, including sidewalls 14, and rear and front walls 16 and 18, respectively, of the same height, and a top wall 20. An opening 22, shorter than the length of the front wall 18, is formed therein to the bottom wall 12, and an ash drawer or pan 24 slides through the opening 22 upon the bottom wall 12. The pan 24 has sidewalls 26, and a front wall 28, provided with an exterior bail handle 30, but is devoid of a back wall, the rear end of the sidewalls 26 being rounded off at their upper corners, as indicated at 32, to facilitate placing and removing of the pan. In addition, a pivoted bail 34 is secured, at 36, to and extends between the sidewalls 26 near the rear ends thereof, for convenient handling of the pan 24, when removed from the base 10.

Upstanding upon and suitably secured at its lower end to the top wall 20 of the base 10 is a vertically elongated Patent 0 Patented Sept. 26, rear cylindrical casing 38, having a sidewall 40, which is preferably corrugated, as at 42, for strength and rigidity, and an open upper end 44. The casing 38 is preferably of a diameter equal to the width of the base 10 and is centered thereon. Fixed on the upper part of the sidewall 40, at

. the back of the casing, is an upwardly and outwardly flared flue box 46, which extends spacedly around and encloses a flue opening 48 in the sidewall. The box 46 has a top wall 50 having an opening 52 therein which is surrounded by an upstanding neck 54, over which is sleeved the lower end of a removable perpendicular stack 56, which is secured by suitable means, as indicated at 58.

Fixed on the upper edge of the casing sidewall 40, and centered with respect to the flue box 46, is an abbreviated semi-elliptical top wall 60 having a straight forward edge 62. An upwardly swingable flat cover 64 for the open upper end of the casing 3 8 is circular, except for a segment equal to the area of the abbreviated top wall 60, and has a straight rear edge 66, which abuts the top wall edge 62 when the cover is closed. Hinges 68 having leaves severally secured upon the upper sides of the cover 64 and the top wall 60, hinge the cover on the top wall 60. A rigid bail handle 72 is fixed to the upper side of the cover 64 and extends forwardly from the cover.

The lower front part of the casing sidewall 40 is formed with a circumferentially elongated rectangular emptying opening 74, and a tangential, radially outwardly projecting frame 76 is fixed to the sidewall 40 around the opening 74, and extends downwardly to the top wall 20 of the base 10, the frame having first and second end walls 78 and 80, respectively. A door 812 is hinged, as indicated at 84, on the frame end wall 78, for closing the open outer end of the frame 76. The lower part of the door 82 has draft openings 86 therein. A horizontal latch bar 88 is centrally pivoted at one end on the outside of the door, as indicated at 90, and has a free end 92 which is downwardly engageable in a notch 94 in a keeper 96 which extends forwardly from a basket 98 which is fixed on the second frame end wall 80, to keep the door 82 closed. A spring 100 is stretched between a lug 102 on the door 82, below the closed position of the latch bar 88, and a lug 104 on the latch bar near its free end, and serves to hold the latch yieldably in its latched position in the keeper notch. An L-shaped handle 106 is fixed to the middle of the latch bar 88 and has a grip 108 which extends away from the spring 100, toward the hinge 84.

The illustrated incinerator further comprises a circular grate assembly 110, which, as shown in FIGURES 3 and 4, comprises a rectangular, centered diametrical and flat grate 112, having parallel spaced grate bars 114 extending lengthwise thereof, and semi-elliptical, imperforate ramp plates 116 which have straight inner edges 118 which are fixed to the opposite sides of the grate 112, as indicated at 120.

The ramp plates 116 are angled inwardly and downwardly to the grate 112, as shown in FIGURES 2 and 3, so as to gravitationally convey to the grate 112, from opposite sides thereof, any material deposited upon the grate assembly 110, through the open top of the casing 38. As also shown in FIGURE 2, the ramp plates 116 have the same forward and downward angulation as the grate 112, but stop, at their depressed ends, at the emptying opening frame 76, while the depressed end of the grate 112 extends therebeyond and into the (frame 76, to the bottom wall 122 of the frame and the bottom of the opening 74. The grate 112 has an arcuate rear end bar 124 which conforms to the curvature of and bears securably against the back of the casing sidewall 40; and a 3 straight forward end bar 126 which rests upon the frame bottom wall 122. I,

A suitable burner, such as a gas burner 128, is supported centrallyand immediately beneath the upper part of the grate 112, on brackets 130- and 132 upstanding on cross bars 134 and 136, respectively, which are fixed at their ends, as severally indicated at 138, to the casing sidewall 40, The burner body 142 is elongated lengthwise of the grate 112, and is disposed at the same angle as and parallel with the grate. The burner has a fuel pipe 144 and a burner regulator shaft 146 leading rear- Wardly therefrom through the casing sidewall 40.

In operation, trash, including incombustible and combustible material, having been deposited in the casing 38, falls upon the grate assembly 10, and the ramp plates act to convey material thereon onto the grate 112, to the region of the burner 128, the incombustible material, such as cans, bottles, and the like, sliding down along the grate 112 to the lower end thereof, and piling against the door 82, so that this can be removed simply by opening the door 8 2; and the combustible material being reduced to ash, by the burner, which falls through the grate 112 and through a grate-size opening 148 in the base top wall 20, into the ash drawer.

While there has been shown and described herein a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claim appended hereto.
